Translate ip range

Good afternoon everyone, I am facing the following problem:

I created an SSTP VPN for communication between head office and branch, I would like the IP range 192.168.0.0/24 of the head office to be displayed as 192.168.100.0/24 in the branch’s mikotik, in order to avoid conflicts. For this I am trying to use NAT rules with NETMAP but I am unable to establish this connection.
Accessing the IP range 192.168.0.0/24 is working, so I imagine the problem is my translation to .100.x in the matrix mikrotik

Could you help me solve this problem?

Hello and welcome to forum
You probably have to post your firewall rules, including filter ones, so we don’t have to guess what you have already done and what can be wrong with it.
